The age of space science began less than thirty years ago.But already people have made great discoveries and have done exciting things.They have walked in space,visited the moon,and lived in space laboratories for long working on ways to make it possible for people to periods of time.Some scientists are now live on other planets.They are trying to solve problems of living in space,even though they don’t yet know what all of the problems will be.For example,they don’t yet know what problems people would have if they loved being weightless for several years.If you were a space traveler you might have to spend several months,or even years in a spaceship.While you were in the ship you wouldn’t live as you usually do.You might have to find new ways to spend your time.Your body would have to adjust to different conditions.And you would have some problems that you never think about here on Earth.For example,you would have to have a huge supply of food with you because you can’t go to the supermarket when you’re halfway to another planet.You also would need fresh water and a way to get rid of waste.In fact,there would be many problems to solve in order to live in space.3.The phrase "a huge supple of food" means_____A.a huge piece of foodB.the food that is largely supplied on the marketC.a large amount of foodD.the food at the supermarket4.While you were in the spaceship,you would NOT__A.need fresh water and a way to get rid of wasteB.have some unusual problemsC.go to the supermarket when you were halfway to maother planetD.find new ways to spend your time
